I climbed a pole and used my proximity voltage detector to test the strand that I was working on. Test OK so I proceed to test line and I come down looking for the open at 180 feet on my phone cable. I walk the line and look up to see a 3 wire Edison power braid going to a house that is laying across my strand! If that insulation would have been bad, It could have energized the whole strand with me included. Although the strand is grounded, it would not have been pleasant. Once asked a pool construction guy in a bobcat if he had called USA to mark the underground utilities (as I was pointing to a severed 50 pair cable coming out the side of the pool dig) He said there was nothing back here and I then proceeded to show him an underground Edison vault that was under an inch of dirt and 6 inches from the side of the pool excavation. All utilities were buried in this tract and they all went through this guys yard, no marking was ever called for and he got a $1,700 bill from us to repair the line and customers down time.
